THE HIGH FREQUENCY SURFACE WAVE RADAR SOLUTION FOR VESSEL TRACKING BEYOND THE HORIZON

, 2019
With maximum range of about 200 nautical miles (approx. 370 km) High Frequency Surface Wave Radars (HFSWR) provide unique capability for vessel detection far beyond the horizon without utilization of any moving platforms.

Propagation modeling and path loss prediction tools for high frequency surface wave radars

, 2010
Propagation modeling and simulation approaches for the use of High Frequency Surface Wave Radar (HFSWR) are discussed. HFSWR uses vertically polarized surface waves along multi-mixed paths in the lower HF band (3 MHz - 15 MHz).

Generalised noise cancellation method for wave estimation by HF surface wave radar

, 2014
High frequency (HF) surface wave radar (HFSWR) has been demonstrated, in many experiments and papers, to be a powerful tool for sea-state detection. However, the availability and accuracy of the HFSWR measurements are limited by various unwanted clutter ...

Radio frequency interference cancellation for sea-state remote sensing by high-frequency radar

, 2011
High-frequency surface wave radar (HFSWR) has been widely adopted as a useful remote-sensing tool for sea-state monitoring. There are limitations to the performance because of various unwanted clutters and interferences that contaminate radar signals ...

High-Resolution Sea Surface Target Detection Using Bi-Frequency High-Frequency Surface Wave Radar

The monitoring of the sea surface, whether it is the state of the sea or the position of targets (ships), is an up-to-date research topic. In order to determine localization parameters of ships, we propose a high-resolution algorithm for primary signal ...

A New Generation of HF Surface Wave Radar

International audienceA primary function of a radar is to monitor a given area. For surface radars, the monitored area is limited by the horizon due to the Earth's curvature. To overcome this limitation, several concepts of HF Over The Horizon Radar (OTH-
